I got this product from the same place as 'slivka81' (a reviewer below), so I can't complain about the price! -Most drug store mascaras are way over £5, these days, plus I can actually see the quality in this mascara. I've used lots of high-end macaras to date- including Giorgio Armani Eyes To Kill, ones from YSL, Dior, Chanel, D&G, Shiseido, Givenchy etc and I have to say this one still had the ability to impress. I like the fact this treatment gives a colour (I got the 'Midnight' shade, which is a very dark blue) which is good for my blue/grey eyes, helping to bring out there colour more (black mascara just makes my eyes look dark and colourless). I currently use this with my Dr.Hauschka and MAC Zoom Fast Lash mascaras (but to be honest, I don't think it matters what mascaras you use this with as it gives its own effect), and it doesn't clump at all. It just gives beautifully separated and lovely long lashes without looking messy or tacky. I'm really impressed and I am glad I bought it. I have always used a lot of mascaras (up to four on my lashes at one time) but using a lash extending treatement really makes the effect more sophicated and tidy looking, which is great for an office look-and lasts all day for me, so using this has converted me to using lash extending treatments more in future.
